A Ultimate Guide of Containerization Technology

Published on October 25th, 2023

Cloud-based infrastructure on demand has transformed the way organizations can expand their services and products. What is this all about? There is no requirement to completely overhaul your infrastructure of apps, while introducing new features or expanding it as you would like it to be. It is well known that the proactive monitoring and management of your enterprise IT infrastructure is the necessity of the moment.

What if we tell you that there’s a possibility to install an emulating Operating System (OS) inside an existing system and mimic its functions as if it were a completely new system? Simply put, how would you run an OS within one of your existing OS? It could save lots of time in developing and money in addition to ensuring the uniformity of code across all the developer systems throughout your infrastructure for applications.

So, the answer to these questions is in fact containerization technology. Let’s first examine the definition of containers, their technology and then how you can cut development costs by effectively making use of containers.

What is Containerization Technology?

The technology of containerization, in default, is a result of the enhancements of virtualization. It is also referred to as an OS-level virtualization. It’s a bit confusing, isn’t it? Let’s look at it in detail.

Containerization is about packing the requirements of an application that is in development into an image base. The application can be run as it’s own space (containers) across different platforms. It is essential to note that the containers run on the same operating system. The majority of IT executives are fascinated by this technique because it is commonly utilized to deploy and run an app distributed without needing the use of the Virtual Machine (VM).

Virtual machines face the issue of code that is prone to errors while moving the application’s infrastructure from one environment to a different one. For instance, a majority of enterprises were unable to develop apps when a developer shared development files from Linux to Windows-based OS.

It was in 2013 that Docker became available, to solve the problem by disrupting the software development process. It enabled Linux-based software to effectively run on Windows-based platforms through Docker. While it was still a theoretical concept at the time, Microsoft was the first to implement this in the year 2016. Since then, a variety of websites and major tech giants like Shopify, Pinterest, Riot Games and many others have adopted containerization technology. It is widely used to benefit from the advantage of DevOps.

What are Containers used for in DevOps?

What impact do containers play? What impact do containers have with DevOps? Like we said, containers are an image base. The image could be shared across the organization by the operations team, developers and everyone else who is involved in the project.

The entire schema is an updated methodology of DevOps, where containers are used to connect different teams as well as the necessary operational and development files. The mythology of connecting and deploying new features in an app quicker, containers were born. They are Continuous Integration (CI) and Continuous Delivery (CD). The three primary factors that affect containers to be a part of DevOps include,

Dependency: Libraries, configurations, runtime engine, program tools, etc. of an application can be shared among many systems that run identical OS. Collaboration is improved!

Disposability It is easy to extract any app or data from a system and then remove the entire application from running in the event that the system doesn’t require any additional. It reduces expenditure!

Concurrency The use of CPU energy effectively, in contrast to virtual machines. This has been proven to develop auto-scale capabilities for any model of architecture, particularly when using cloud computing. Improves automated development!

Expert Analysis: For example, through the use of Docker to act as a container the code that is written in Linux could be transmitted to a Windows system. The Linux-based program doesn’t require any additional tools, libraries, system software and runtime native code or settings for running on Windows while developing. Sometimes, even without the infrastructure! What’s so convenient?

Containers are made of different types

There are currently many options that you can choose from in terms of container technology. Docker is among the containers that could ring a few bells. However, it’s disastrous when your app were to be misinformed about the various types of containers in use due to the rapid growth and expansion of containers recently.

In 2015, due to the increasing popularity of container technology, the Open Container Initiative (OCI) made the decision to keep the requirements and specifications for container technology to ensure that businesses have more options to select from the open-sourced and diverse selection of container engine options available in the present. Some of the most popular examples are listed below:

Docker

A containerized open-source platform that integrates the app’s source code along with the current OS and the associated dependencies and libraries. The code can run on any computer system.

LXC

A container that runs on OS, which allows the application to run on different Linux systems at an unintentional basis, provided it is running one Linux kernel which acts as host OS.

CRI-O

It’s a container Runtime Interface (CRI) for Kubernetes, the cloud-based container management system. It’s a CRI designed to ensure that it adheres to OCI runtimes compatible with the OCI. Therefore, this tool can be used as a replacement for Docker that is based on Kubernetes.

rkt

A container engine that is based on applications known as Rocket is utilized to build modern cloud-based applications. It utilizes CoreOS that operates by leveraging the security enhancements that previous version of Docker were reputed to have. It’s best to use it in conjunction with the necessary technology or as distinct components of the Docker-based system.

Benefits of using Containerization Technology

Containerization technology is spreading rapidly across various industries, with a particular focus on companies that depend on cloud-ready applications. Even if your app isn’t cloud-ready, or cloud-native, there are some advantages of containerization that you could reap.

• Reduced infrastructure costs because many containers can be run on a single computer and even on the Virtual Machine (VM).
• Applications that are monolithic or older could be encapsulated using microservice architecture, allowing for future expansion.
• Enhances security of applications as the app will be kept within separate container on multiple platforms and isolating the host.
• Containers do not require any specific OS and are able to be used on any OS as long as the container engine is running on an host OS.
• Containers are light and speedier since they’re prepared for processing in just a few seconds.

Where can you utilize technology for containerization?

It could be the implementation in DevOps and moving to the cloud and you might be thinking what are the potential uses of containers? Containerization technology is able to aid in developing any app that would have been difficult to develop on a native system. Some of the key containers used in applications are listed below.

• Refactoring Applications

Containerization technology plays an important contribution to helping the development and operations teams make use of techniques of lift-and-shift during the transfer of applications or architectures needs.

• Support for CI/CD

Containers allow you to make a simpler development process that allows for building tests, dispersing changes or new features often with ease. Furthermore, it minimizes the number of tests and stops the formation of a continuous clustering of file transfer across different systems.

• Compliment Microservices

Make it easier to develop and deliver the process of Microservice applications using containers since they are able to isolate the environments for work. Separating an architecture from its independent work environments is easily created.

• Web Server Dependence

Containers don’t need to be run in a direct manner in the host. It can instead be run on any device and the only requirement is to make sure that your host’s OS remains identical across all systems. Since it is only the space of a few commands, a web server could be created inside the container.

How Does Technology for Containerization Work?

Let’s look at how containers function without over complicating the process for you. Containers generate images of codes that are written on a particular system and the settings that it has libraries, dependencies and libraries. These images run as containers that can be run on any platform.

Containers aim to isolate the program from various computing environments. This allows you to run a program consistently or in a uniform manner across different platforms, regardless of the different staging environments and processes for development.

Containerization technology is also used as an OS host. However, they aren’t duplicates of a parent OS like we mentioned earlier. Take a look at the following image.

The Containerization myths that are commonly cited

It is important to weed out any misconceptions about containerization prior to attempting to figure out the details of what they are.

This section will discuss some of the most common misconceptions of containerization and containerization in DevOps.

How can companies cut costs through Containerization?

While both VMs and containers are focused on the same idea of virtualizing the same computing resource, the container is typically selected over VMs. Why is this? In simple terms, VMs consume more overhead in comparison to containers.

Virtual machines allow businesses to operate multiple servers from one system, or even more, regardless of the OS. Contrary to that, containers are light in weight and allow virtualization of applications with the capability to set up instances and shut them down in just a few minutes. Let’s take a look at the advantages of containers. we begin by discussing the issues that arise with virtual machines and the ways that containers can aid in reducing development costs.

Problems that have to be overcome prior to the introduction of containers

• Performance

In a VM the development-related resource is usually transferred from hardware to the virtual platform. However, this can result in resource depletion in a much faster pace, referred to as VM saturation. This ultimately causes the application to suffer slow performance.

• Awareness

Despite the fact that containers exist even today, VM is still widely thought of as a new concept by many IT firms. The majority of developers don’t understand VM to be a device used to virtualize apps. VM is a tool to virtualize an OS however that does not mean that it is able to create a virtual app within it. These fundamental confusions can lead to issues such as,

• Develop an unsuitable app infrastructure
• It is possible to lose IP addresses as you migrate the application between different systems
• Incorrect assignment of the bundle images to the incorrect VLAN

• Storage

The process of virtualizing the OS drive is a sign that an OS drive must be converted into the format of a flat file, i.e., Virtual Machine Disks (VMDKs), that can be more than 100GB in some situations. Furthermore, VMDKs may not be necessarily utilized by all development systems and inactive files are costly storage. And that’s not even counting the number of files that need to be kept.

How can Containerization Technology help Overcome Obstacles?

Although a VM and a container both permit organizations to adjust to rapidly changing environments Containers offer better ways to offer new services and create new products rapidly. Containers work better, and overcome the typical issues by VMs as mentioned earlier. One of the most important solutions that containers provide are

• Containers permit sharing of host OS which makes it lighter and less expensive in terms of use for the development phase and for deployment.
• The size of the container image is usually in megabytes, not gigabytes when compared to the image that is generated by the help of a VM. Reduces costs for storage.
• Making any function work with containers is possible in milliseconds. This can reduce the time to develop.
• In comparison to VM and VM, one system is able to host multiple containers that can be used to transfer development data to another container on a different system quicker. This means it will require less IT resources to manage, operate and deploy.

A few of the methods where containers are specifically designed to increase the value of your product include,

• Increase your market share by using faster advancements in techniques.
• Ability to conduct further research, test and create prototypes in a short time.
• App components can run in a variety of ways, whether on cloud storage as well as local storage or both.

This is only the beginning of the iceberg. everything above will ensure that the solutions mentioned above aid businesses in scaling effectively. As decision-makers, you’ll be able to test something completely new. If it is successful the idea can be incorporated into the production process.
